Description
Technical field
The present invention relates to a kind of additive to regulating and controlling the application of slag viscosity during non-ferrous metal pyrometallurgical smelting, belong to and have
Non-ferrous metal technical field.
Background technology
At present, the non-renewable mineral resources of China are the most exhausted, and existing mineral products are also that rich ore is few, lean ore is many,
Head grade is low, selecting and purchasing is difficult, but the slag but bulk deposition smelted, not only land occupation but also pollute environment.In slag possibly together with
Substantial amounts of valuable metal, has higher value.Therefore, this part valuable metal recycled in Waste Slag has
The highest economic worth.Traditional non-ferrous metal pyrometallurgical smelting process utilizes carbonaceous reductant or changes slag type regulation and control slag
Viscosity is so that slag and metal preferably separate.But carbonaceous reductant can cause high carbon consumption and high carbon emission, its consequence is
Global warming and climate disaster, carbonaceous reductant also has the shortcomings such as reduction efficiency is low, production cost is high, seriously polluted simultaneously.
By adding a certain amount of flux, change the slag type of slag, it is achieved valuable metal and the separation of slag, there is slag, gold separation effect
The problem that the poorest, metal recovery rate is low.Accordingly, it would be desirable to develop a kind of regulation and control method of non-ferrous metal pyrometallurgical smelting slag viscosity,
Realize smelting process resource, clean, low carbonization.
In the pyrometallurgical smelting process of copper, the method for conventional dilution smelting slag has electric dilution and reverberatory furnace dilution side
Method.In molten bath, typically add coke or in molten bath, spray into, by air port, the magnetic that fine coal, natural gas etc. come in reduced blast furnace
Iron Oxide Minerals, makes copper preferably separate sedimentation with slag.Its shortcoming is: use the solid additives such as coke to contact with slag
The most fully causing percent reduction low and consumption is big, produce substantial amounts of greenhouse gases, environmental pollution is serious；Use natural gas etc.
The reduction efficiency of additives gas is high, but its condition of storage requires higher, and security incident easily occurs under high temperature；Use the liquid such as diesel oil
Body regulates and controls the magnetic oxygenated iron mineral in the reduced blast furnace of slag, although easy without potential safety hazard under its reduction efficiency height and high temperature
In storage, but the diesel oil of about 2L to be consumed ability one ton of slag of dilution, add production cost and energy consumption.Lead liquid
Slag Direct Reduction Technology is most widely used in the smelting process of lead, and this technology not only energy consumption is low but also processing cost is the most relative
Relatively low.At present, also some producer uses the high lead slag direct-reduction technique of liquid heat to substitute retailoring of blast furnace, this
The difference of technology maximum is to use coal dust to carry out substitute for coke reduction in fusion process, although processing cost is further
Reduce, but have ignored that coal dust reduction efficiency during reduction melting is low, energy consumption is high, and environmental pollution and seriously this
One shortcoming.The reducing agent that the stannum of China and the reduction melting of zinc use at present is mainly coal dust.Tin-smelting plant mainly passes through Ao Simai
The bath smelting equipment such as special stove, reverberatory furnace and electric furnace use " Tin concentrate reduction melting-thick stannum pyro-refining-solder electrolytic or true
Empty distillation-stannum slag fuming process " technological process carry out tin metallurgy, and the zinc leaching residue of zinc hydrometallurgy output is typically also adopted by molten bath
The method of smelting reduction volatilization processes, and reclaims valuable metal therein.No matter it is tin metallurgy or zinc metallurgy, their maximums common
Point be exactly reduction melting be all that percent reduction is the highest as reducing agent with coal dust, consumption is big, directly results in production cost and improves,
And use coal reduction to produce the flue gas that a large amount of environmental pollutions are serious.
Biodiesel is to pass through ester exchange reaction and ester for raw material with alkylol with animal and plant oils and fats, microbial grease
Change the long-chain fatty acid mono alkyl ester that reaction generates.Biodiesel is the biomass energy of a kind of green, has recyclability, tool
There are environment superperformance, degradability；And make cheaper starting materials and be easy to get, there is good development prospect.Vegetable oil lipoprotein be by
The natural polymer that fatty acid and glycerol are bound up, is widely present in nature.Every from plant seed, sarcocarp
And the fat obtained by other extracting section is referred to as Vegetable oil lipoprotein, and Vegetable oil lipoprotein is clean reproducible energy, with biology
Diesel oil is similar, and raw materials for production are cheap and easy to get, and production cost is relatively low.Waste oil refers to all kinds of poor oils present in life,
After a part is reclaimed by illegal retailer, extracting through simple technique and come back on dining table, long-term absorption is by different for induction journeys
The health condition of illness of degree, such as insomnia, dyspepsia, the symptom such as anemia, severe patient also can cause alimentary toxicosis, carcinogenic etc., even can
Threaten life security.So waste oil being converted into biodiesel or being directly used in commercial production, can effectively stop
Waste oil entrance food chain returns to mankind's dining table and alleviates the environmental hazard that waste oil causes, and waste resource can be made again again to obtain
Utilize and realize truly energy-conservation.Therefore, develop a kind of hybrid-type new additive agent, for the regulation and control of viscosity, there is work
Industry application prospect and huge economic worth.
